Alicyclic dianhydride CBDA is mainly used as monomer for polyimide film, resins and varnish, especially CPI, Alignment layer monomer, Flexible display, Transparent flexible circuit board, Electronic level CBDA, High transmittance > 89%, Low Yellow Index < 2.0 –> Colorless and High Transparency.

cyclobutane-1,2,3,4-tetracarboxylic dianhydride and diamine monomer are used for preparation a polyimide (PI), the type of polyimide has excellent electrical characteristics and optical type, with the material prepared the PI film, in addition to having a higher rate cast visible outside, and can withstand high temperatures thirty-four Baidu. Its performance is very good, is the preparation of a liquid crystal display with an ideal material for the film.

Reactant for:
Preparation of biologically and pharmacologically active molecules
Preparation of photosensitive polyimide material for high performance organic thin-film transistors
Selective crosslinking of polyimide for photonic devices
